Part0: Learning Swift6 for Complete Beginners Through Problem Solving (Free, 2025, Perfect XCode 26 Support)

Hello, I'm agmma, a current iOS developer

I started studying development at 31 while doing other work, and I'm currently working hard as an iOS developer at a subsidiary of one of the major Korean tech companies (NAVER, Kakao, LINE).

• Started studying development at a bootcamp in early 2020 (age 31)

• Got a job as an entry-level iOS developer at a subsidiary of one of the major Korean tech companies (NAVER, Kakao, LINE, Coupang) at the end of 2021 (age 33)

• Currently working at the same company as of 2025

As someone who started development at the late age of 30s as a non-major, I deeply empathize with the overwhelming feelings and difficulties that those preparing for employment face more than anyone else. I also understand well the efforts of those who are preparing for career changes by dedicating their precious time for continuous growth.

Having spent two years with no income, running solely toward the dream of becoming a developer, I want to provide high-quality lectures at reasonable prices to those walking a similar path.

Although not all of the curriculum has been completed yet, when all the lectures I have planned are released, if you consistently follow my lectures, you will be able to acquire all the knowledge needed as a 1-2 year iOS developer, and I will create them with that sense of responsibility.

📖 E-book Preview

The image shown below is a capture of some content from the free e-book that will be provided with this course.
Since it contains the exact same materials used in the actual lectures, students can review following the same flow as the course.

This e-book is not a simple text summary.

• Key Concept Summary: Systematically organized essential content that must be remembered from the lectures

• Various example codes: Includes code samples that you can follow along with to broaden your understanding

• Visual materials and diagrams: Schematized to make even abstract concepts easy to understand

• Review Questions: Enable self-directed learning by checking what you've learned

Therefore, the e-book is not simply reading material, but rather a supplementary textbook that allows you to practice and review alongside the lectures to maximize learning effectiveness.

Through this free e-book, even those who are just starting development will be able to learn Swift and iOS more deeply and systematically.

📝 More reliable through problem-based learning!

Programming language lectures can easily feel rigid and boring.
That's why this lecture doesn't just stop at explaining concepts, but is structured so that you can think and solve problems directly by adding practice problems for each concept.

💡 If you simply listen to lectures and only learn concepts, they tend to just pass through your mind and are easily forgotten.
However, by solving practice problems, you can check what you just learned on your own and experience knowledge becoming truly yours.

Additionally, the problems are not simple memorization-based, but include situational problems linked to actual Swift code, designed to naturally develop practical skills.
In other words, through the lecture → problem → solution process, you can complete the learning cycle of concept understanding → application → self-assessment.

The photos shown below are actual examples of practice problems included in the course.
By solving these problems, you won't just be a "passive learner," but rather a developer who actively participates and grows. 🚀

💻 Perfect Xcode 26 Support

This course "(Free) Learn Swift by Solving Problems (2025, Perfect Xcode 26 Support)" was created with perfect support for Xcode 26, the latest version as of August 2025. 🚀
Therefore, all example code and practice materials covered in the course work normally in the Xcode 26 environment.

Currently, Xcode 26 is available as a beta version, and to use it, you need the latest beta version of macOS, macOS Tahoe. 🍎
Therefore, those who want to experience the latest technology as quickly as possible can follow the course content exactly in the beta environment.

However, since the official version has not been released yet, you don't need to worry.
👉 There are no issues at all with taking the course in the existing Xcode 15 environment, and you can learn all the code and concepts without any problems.

In other words, this course has the following advantages:

• ✅ Perfect compatibility with the latest version (Xcode 26) → Experience the latest development environment

• ✅ Compatible with existing version (Xcode 15) → Learning possible in a stable environment

• ✅ Production considering future updates → Can be utilized as-is even after the official version release

📌 In conclusion, this course is the fastest option to learn Swift and iOS development in line with the latest trends.
"A course that allows hands-on practice even in the latest beta environments while being easily followable in stable existing versions" — this is precisely the greatest strength of this course. 🌟

🚀 8 hours 43 minutes, free but with quality beyond paid courses

This lecture is a free course prepared with a total runtime of 8 hours and 43 minutes.
I never thought "I'll make it simple because it's free." Rather, I aimed for quality that's comparable to paid courses. ✨

📌 This course is not just a superficial overview of basic grammar.
From Swift fundamentals to core concepts essential for iOS development, everything is covered systematically and comprehensively.
It literally covers almost everything about Swift and is designed to help beginners build a solid foundation.

🕐 During the total learning time of 8 hours and 43 minutes, you will experience the following:

• 🔑 Step-by-step learning from Swift basic syntax to structures, classes, and optionals

• 💡 Hands-on practice with example code that can be directly applied to real development

• 📝 Master each concept through the included practice problems for every topic

• 📘 Maximize learning effectiveness with review using free e-books

Therefore, by completing this course, you can grow beyond simply knowing a bit of Swift to become a prepared developer ready to actually start iOS development. 🌱

👉 Although it's a free course, the vast knowledge and hands-on experience provided over 8 hours and 43 minutes contains value that's hard to believe is actually free.
